2 Legislative framework D.M. 185/89 - Regional Remediation Plans: inventory includes now over 12,000 potentially contaminated sites D.Lg.vo 22/97 - Waste Act (Decreto Ronchi) D.M. 471/99 - Technical regulation for cleanup of contaminated sites L. 426/98, L.388/00, L. 468/01, L. 179/02: the National Remediation Plan includes now 50 Sites of National Interest

3 Contaminated sites progress Regional plans Remediation status of contaminated sites in Italy Characterization study Assessment in progress Remediated Total North Centre South Islands

6 Regions - Piemonte soil treatment technologies Excavation and landfill disposal Landfarming Biopile Natural Attenuation Thermal treatment Bioventing / SVE O.R.C. Capping Chemico-physical inertization

7 Regions - Piemonte groundwater treatment technologies Pump & Treat Natural Attenuation Air sparging Reactive barriers

8 Sites of National Interest care of Ministry for the Environment 50 sites identified so far Surface of 4 sites alone is 702,522 ha (land/sea/surface water) > 2 % area of national territory Costs estimated (over 41 sites): 3, M Government Funds (over 41 sites): M (17,4% of estimated requirement) Several investigation and emergency safety actions projects have been authorized together with few remediation projects

9 Geographical distribution - Sites of National Interest Islands 16% North 35% South 30% Center 19%

14 Sites of National Interest Activity type Site complexity - presence of more plants and /or activity categories very complex 12% extremely complex 6% medium complex 8% less complex 16% simple 58%

17 Sites of National Interest Remediation progress Sites of national interest remediation status 12% 2% 30% 30% 2% Formally identified but not yet delimited Delimitation of potential contaminated area Safety actions taken Characterization study Assessment in progress Remediation in progress 24%

18 Example of a National Interest Site Acna di Cengio (chemical manufacture) ACNA Cengio - indicators of the characterization study boreholes samples (soil) samples (gw) samples (sw) analytes Public area Private area

19 Conclusions Much effort is dedicated to characterization and assessment of Sites of National Interest Remediation: Few off-site soil treatment plants are available because present legislation limits off-site soil treatment and reuse Excessive dig&dump/containment/no soil reuse are also a consequence of severe soil standards and legal restrictions and poor application of risk-based solutions Groundwater remediation 60% is P&T; few PRB and NA cases Improving: participation in multinational research projects, education and professional expertise.
